Straight teeth are easier to clean. Proper bite puts less stress on teeth. So straight, easy to clean teeth = less caries, less gum disease, less wear, less cracked teeth, and longer lasting teeth (if you do your part).
Like saying America is obsessed with oil changes and tire rotation. Want your car to last longer?
My first trip to South Africa in 1988, my PH met my plane in Kimberly on the tarmac. As we deplaned and walked down the stairs a man I'd never laid eyes on walked right, called me by name up and introduced himself. I asked how he knew which one was me?
"I can spot an American smile away. Straight teeth and white tennis shoes"
